Title: Container, method, arrangement for manufacturing the same
Inventor: NILSSON TORSTEN
IPC: B29C49/18
Filed: 1985-12-10
Granted: 1991-04-16
Abstract: ABSTRACT            A hollow body (e.g. a container) as well as a method and an apparatus for its manufacture in which an axially directed wall of the body primarily comprises oriented and/or crystallised plastics material. A tubular preform (10d) is fixed in a circumferential region (13d) in the vicinity of the mouth edge (14d) of the preform between mechani-cal forming devices (30,40), after which the devices, during con-tinued clamping of the circumferential region, are displaced in the axial direction of the preform relative to a mandrel (50). Thus, the mandrel is displaced into the preform during simultaneous expansion thereof and the material is oriented and/or crystallised. In a pre-ferred embodiment there is made a certain compensation of the stretch-ing forces, which arise in the material when inserting the mandrel, by applying a force to the bottom of the preform by a bottom support (75).

Title: Tube-shaped container
Inventor: BAYER MICHAEL
IPC: B65D51/22
Filed: 1986-02-14
Granted: 1991-09-24
Abstract: A B S T R A C T            Tube-shaped container The tube has a peg-shaped neck extension (3) at its upper end, which contains a predetermined breaking point (4).   The neck extension (3) is generally positioned under the removable protective cap (7).   A short socket (9) is formed on the upper side of the cap (7) in an axial direction, the interior diameter of which is slightly greater than the diameter of the neck extension (3).   The inner surface of this socket (9) and the outer surface of the neck extension (3) are provided with corresponding notch flanges (5) or notch grooves (10), such that the cap (7) and the neck extension (3) are non-positively connected to each other when rotated about the longitudinal axis, when the cap (7) with the socket (9) is positioned on the peg-shaped neck extension (3).   If the cap (7) is rotated in this position about the longitudinal axis with slight pressure simultaneously exerted then the peg-shaped neck extension (3) is sheared off at the predetermined breaking point (4) and the tube is thereby opened.   The cap (7) thus acts as protective cap on the one hand and as a tool for opening the tube on the other hand.

Title: Tachogenerator
Inventor: RODI ANTON
IPC: G01D5/245
Filed: 1986-11-06
Granted: 1991-09-24
Abstract: ABSTRACT           The invention relates to a tachogenerator of compact  con-struction with  a  hollow  shaft  connection  and  a  clamping element for fixing  said tachogenerator on a rotating drive shaft. The stator of the tachogenerator is  connected to a stationary  machine  part  in  order  to  be  secured  against distortion.  Said  hollow  shaft  connection  is  part  of  the rotor and is arranged on the drive shaft so as to be fixed against  rotation.  The  stator  is  mounted  on  said  rotor, which  bears  the  coding  disk,  via  bearings  so  as  to  be freely  rotatable,  whereby the rear  face  of  the  rotor  is brought in plane contact with a shaft collar of the rotat-ing drive shaft by the clamping element. Placing the hollow shaft  connection  into the bore  of  the  tachogenerator and mounting  said  tachogenerator  directly  on  the  drive  shaft results  in  a  reliable  and  maintenance-free  arrangement, which excludes any reverse play, and in an extremely com-pact construction of the drive.

Abstract: TITLE                  METHOD OF MAKING SHAPED CERAMIC COMPOSITES         WITH THE USE OF A BARRIER                   APPLICANT                       LANXIDE TECHNOLOGY COMPANY, LP                                  INVENTOR                      Marc S. NEWKIRK and Robert C. KANTNER                           ABSTRACT OF DISCLOSURE In the present invention, there is provided a method for producing a self-supporting ceramic body by the oxidation of a parent metal to form a polycrystalline ceramic material consisting essentially of the oxidation reaction product of said parent metal with an oxidant, including a vapor-phase oxidant, and optionally one or more metallic constituents. The method comprises the steps of providing at least a portion of said parent metal with a barrier means at least partially spaced from said parent metal for establishing at least one surface of the ceramic body, and heating said parent metal to a temperature above its melting point but below the melting point of the oxidation reaction product to form a body of molten metal. At that temperature, the molten metal is reacted with the oxidant, thus forming the oxidation reaction product. At least a portion of the oxidation reaction product is maintained in contact with and between the molten metal and oxidant to transport the molten metal through the oxidation reaction product toward the barrier means and into contact with the oxidant so that the oxidation reaction product continues to form at the interface between the oxidant and previously formed oxidation reaction product optionally leaving metal dispersed through the polycrystalline material. The reaction is continued to the barrier means to produce a ceramic body having the surface established by the barrier means. A composite is formed by superimposing a barrier onto a filler material, such as a preform, and infiltrating the filler with the polycrystalline ceramic matrix grown to the barrier means.
